Single-dimension CFD simulation based on an instationary friction model enables precise dimensioning of pump piping systems
Pump manufacturer Lewa is installing a test center for validation of simulation results obtained from their new proprietary software module
A technical animation that visualizes the synchronization of three Triplex process diaphragm pumps in different operating states was one of the highlights at Lewa's booth at this year's ACHEMA show. The objective of this kind of simulation is to reduce pressure-induced pulsation and to prevent formation of pipe vibrations that are...Read more

In order to meet a wide array of requirements, pump manufacturer and system integrator Lewa through their Singaporean subsidiary (LEWA-Nikkiso Singapore Pte. Ltd.) recently fabricated and installed Lewa’s largest chemical injection module ordered to-date, on a Brazilian FPSO off the coast of Singapore.
With dimensions of 21.3 x 20 x 10 m and an estimated operating weight of 714 tons, the complete module surpasses the two others that the Lewa Group has produced for the EPC since 2010. Overall, 2,700 m of pipeline is installed in the module; it can be operated at a maximum pressure of 385 bar...Read more

New touchscreen control for fully automated monitoring and regulation of odorizing systems
In nearly all countries, continuous, proportional odorizing and monitoring is mandated by law for potentially hazardous or highly explosive gases with no natural odor. Lewa GmbH has developed a new Odor Control Unit (OCU) in order to fulfill this need efficiently and without requiring a major commitment of time and personnel. The system continuously compares the target and actual concentration of the odorant, so that regular inspections of the odorizing systems can be discontinued within four weeks, or...Read more

Spreadable butter is one of the primary products of the Danish/Swedish dairy company Arla. At their facility in Gotene Arla is producing the brand Bregott for the domestic market in Sweden. To be able to reproduce the specific characteristics of the different types exactly, ingredients must be precisely metered. For ten years, the production facility in Gotene has used pumps from Lewa GmbH for this purpose, which are not only designed for high discharge pressures but also have an accuracy of ± 1 percent, meeting the manufacturer's strict requirements. From the different variants of the...Read more

On Saturday, 27 June 2015, the 6th Leonberg City Run took place. As in the past years, LEWA supported the 5km- city run as a sponsor and also participated with its own team.
With 1,051 "finishers" (including 299 students) Leonberg City Run broke its own record and could attract more participants than in the previous year (1,004 finishers). In addition to the children run and the students run, a 5 km and a 10 km run took place.
Even before the start of the students runs, the dark rain clouds disappeared, so that the athletes could compete with the best weather. LEWA team’s sportsmen...Read more

LEWA introduces the new triplex process diaphragm pump G3M. With its compact monoblock design and the engine concept with a one-piece crank shaft, the new pump is very efficient. Compared to previous solutions, up to 30 percent footprint and weight can be saved. Thus, the G3M is particularly suitable for applications where space and weight play an important role, e. g. on offshore platforms.
With the new pump, LEWA can respond even better to the customers’ needs and provide the most efficient solution for various applications. As an additional innovation, LEWA offers the option of...Read more

For the Lewa Group, 2014 was another very successful year in terms of revenue and earnings. The company successfully proved its value with numerous large project bids in the oil and gas industries, both onshore and offshore, not to mention in the process industry sector. Despite a cooling market and dropping oil prices, Lewa intends to achieve continued growth in 2015. With regard to Achema, Lewa GmbH, supplier of pumps and systems, has defined three topics of focus with the objective of continuing to expand its position as a technology leader.
"We are particularly proud of the global...Read more

LEWA's parent company NIKKISO developed deep-ultraviolet light-emitting diodes – or shortened: DUV-LEDs. The NIKKISO experts were supported by none other than the two physics Nobel Prize winners in 2014. At ACHEMA, LEWA offers a presentation on development and applications of this technology.
Deep-ultraviolet light-emitting diodes are a successor technology of normal LED diodes. Unlike the conventional LED technology, light wavelengths from 255 to 350 nanometers are possible. In addition to the large light spectrum, an essential advantage is the environmental sustainability: DUV-LEDs are very...Read more
